All prior patents, publications, and test methods referenced herein are incorporated by reference in their entireties.
As used herein, “asphalt shingle waste” is defined as any form of discarded asphalt shingle. “Asphalt shingle waste” comprises, but is not limited to, post-manufacturing waste and post-consumer waste.
As used herein “post-consumer waste” is defined as any waste produced by an end consumer of a material stream. A non-limiting example of “post-consumer waste” is a discarded roofing shingle from a residential or commercial roof. Another non-limiting example of “post-consumer waste” is contractor waste including, but not limited to, surplus new material, damaged material, and scrap from cut shingles during installation. Yet another non-limiting example of “post-consumer waste” is at least one of: distributor waste, retail waste, or any combination thereof, including, but not limited to, damaged shingle products, aged inventory of shingles, and customer returns.
As used herein, “post-manufacturing waste” is defined as waste produced prior to reaching the end consumer of a material stream. A non-limiting example of “post-manufacturing waste” is any shingle waste generated during the production, handling, transportation, or other method of generation prior to installation on a roof of a consumer. Post-manufacturing waste may comprise production waste such as, but not limited to, partial shingles and coated fiberglass mat with or without granules.
As used herein, “asphalt shingle waste powder” is a mixture of particles produced by size reduction steps including, but not limited to, grinding, crushing, or disintegration, the like, or any combination thereof, of asphalt shingle waste.
As used herein, “waste asphalt” is defined as any form of asphalt that is obtained from asphalt shingle waste.
As used herein, a “briquette” broadly refers to any solid agglomeration of particles that comprises asphalt shingle waste powder, asphalt containing powder, or any combination thereof. In some embodiments, a briquette may comprise a binding agent. In some embodiments, a briquette may exclude binding agents. In some embodiments, in any method step where an asphalt shingle waste powder is used, the asphalt shingle waste powder may be partially or completely replaced with a plurality of briquettes.
As used herein the term “briquetting” refers to any process of forming a briquette. In some embodiments, a briquetting process may comprise compressing an asphalt shingle waste, an asphalt shingle waste powder, or any combination thereof, under sufficient pressure, so as to form a briquette. In some embodiments, a briquetting process may comprise the addition of a binding agent. In some embodiments, a briquetting process may exclude addition of any binding agents.
As used herein, “penetration point” is the vertical distance penetrated by the point of a standard needle into asphalt under specific conditions of load, time, and temperature. Penetration point is measured herein according to ASTM D5, unless expressly indicated otherwise.
As used herein, “virgin asphalt” refers to any form of asphalt that is not obtained from asphalt shingle waste. Examples of virgin asphalt comprise, but are not limited to, hot mix asphalt, warm mix asphalt, cold mix asphalt, sheet asphalt, high-modulus asphalt, or any combination thereof. In some embodiments, the virgin asphalt is an oxidized asphalt. In some embodiments, the virgin asphalt is an unoxidized asphalt.
As used herein, “impurities” refer to at least one of fiberglass mat, sand, fines, marker paint, sealant, one or more adhesives, tape, plastic debris, paper debris, soil, wood, nails, or any combination thereof.
As used herein, “phase modifier” refers to a substance that modifies at least one property of an asphalt. In some embodiments, the asphalt is an asphalt that would otherwise not be suitable for use in a roofing application, such as, for example and without limitation, a roofing shingle.
Embodiments of this disclosure can be used to form roofing shingles from asphalt generated from asphalt shingle waste, hard penetration point asphalt, or any combination thereof, by adding a phase modifier to the asphalt shingle waste or the hard penetration point asphalt. As an asphalt ages or oxidizes, the chemistry of that asphalt also changes or evolves. Asphalt is composed of four basic SARA fractions (saturates, asphaltenes, resins, and aromatics) separated by polarity, which combine to form a stable colloidal system. The asphaltenes, which are highly aromatic, contain more heteroatoms, and are higher in molecular weight, are dispersed in the maltene or solvent phase made up of the saturates, aromatics, and resins. The asphaltenes are the main contributor to the internal structure of an asphalt and they dominate the physical properties such as viscosity and rheology. Over time the asphalt in a shingle has undergone the oxidation/aging process described above. Moreover, hard penetration point asphalt also exhibits high concentrations of asphaltenes. Embodiments herein enable usage of the asphalt shingle waste and/or hard penetration point asphalt, by adding a phase modifier to the asphalt, which, in some embodiments, allows for the restoration of the maltene phase and helps re-establish the stable colloidal system.
In some embodiments, an asphalt mixture comprises at least one of a virgin asphalt, an asphalt shingle waste, a phase modifier, or any combination thereof.
